James, Jorge Finally have a good (I think) Fedora 12 rpmbuild kernel as pings thru a LSP between LERs works. However, netperf is failing with "Interrupted system call" on the netperf side (aka netperf --> netserver). Below is the mpls debug ping and netperf output as seen from the netserver side). I need to test using a file seed possible all the zeros is causing mpls some heart burn, I did test doing using FTP which of course ended up only using one LSP but it still worked. I will do that later today using netperf seeded with a file. Is there anything here you observe as strange? One thing that does bother me is some debug output is missing, even with "echo "1" > /proc/sys/net/mpls/debug". Possibly I'm missing something from "sysctl.log" settings? Also, James, many moons ago I reported issues with 10GE running horribly slow. At the time it was assumed when building MPLS-Linux, debug was turned off by default. Ashan's discover suggested another look at the build files when of course I discovered its on by default. So I will retest 10GE LSPs next week. But might I suggest that debug be turned off by default? ...Chris PING TESTS-------------------------------------------------------------------------------------- PING TESTS-------------------------------------------------------------------------------------- PING TESTS-------------------------------------------------------------------------------------- PING TESTS-------------------------------------------------------------------------------------- May 22 06:25:05 FEON kernel: MPLS mpls_skb_dump: from eth1 with len 88 (1832)headroom=48 tailroom=1464 May 22 06:25:05 FEON kernel: 0000000000000000505ca30000000005ffff1f00000100000e00ffff010700002020*00051b70e93700051b00475e8847{# |007d014045000054000040004001e6420a326e010a32d2010800302bd60d000101b1f74b0000000033f6060000000000101112131415161718191a1b 1c1d1e1f202122232425262728292a2b2c2d2e2f303132333435363799} May 22 06:25:05 FEON kernel: MPLS mpls_skb_dump: from eth1 with len 88 (360)headroom=76 tailroom=28 May 22 06:25:05 FEON kernel: 003877360188ffff081077360188ffff081077360188ffff00000000010000004032540200eaffff00000000000000000000000001000000010000000000000000 1077360188ffff08207736{|003e814045000054b3300000400173120a32d201#0a326e010000382bd60d000101b1f74b0000000033f60600000000001011 12131415161718191a1b1c1d1e1f202122232425262728292a2b2c2d2e2f303132333435363700} NETPERF SERVERSIDE TESTS------------------------------------------------------------------------------- NETPERF SERVERSIDE TESTS------------------------------------------------------------------------------- NETPERF SERVERSIDE TESTS------------------------------------------------------------------------------- May 22 06:25:33 FEON kernel: MPLS mpls_skb_dump: from eth1 with len 64 (1832)headroom=48 tailroom=1488 May 22 06:25:33 FEON kernel: 0080a6340188ffff505ca30000000005ffff1f00000100000e00ffff010700002020*00051b 70e93700051b00475e8847{#|007d01404500003c045240004006e2030a326e010a32d201c14032411226796400000000a00216d 0e0800000020405b40402080a00067d36000000000103030732} May 22 06:25:33 FEON kernel: MPLS mpls_skb_dump: from eth1 with len 64 (552)headroom=240 tailroom=16 May 22 06:25:33 FEON kernel: 00b0f9340188ffff050200001f00000012020000061d0b00000000000100000058b1540200eaf fff00000000000000000000000001000000010000000000000001000000000000000000000000000000000000000000000000b1540 200eaffff0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000008010000000625b8{|003e81404500003c000 040004006e6550a32d201#0a326e013241c1401154b13412267965a01216a093550000020405b40402080a00068abb00067d360103030700} May 22 06:25:33 FEON kernel: MPLS mpls_skb_dump: from eth1 with len 56 (1832)headroom=48 tailroom=1496 May 22 06:25:33 FEON kernel: 00a0a6340188ffff505ca30000000005ffff1f00000100000e00ffff010700002020*00051b70e9370 0051b00475e8847{#|007d014045000034045340004006e20a0a326e010a32d201c1403241122679651154b1358010002ed88f00000101 080a00067d3a00068abbcb} May 22 06:25:33 FEON kernel: MPLS mpls_skb_dump: from eth1 with len 312 (1832)headroom=48 tailroom=1240 May 22 06:25:33 FEON kernel: 0080a6340188ffff30007374000062736f6e2f2e636f6e6669672f6d656e75732f73*00051b70e9370 0051b00475e8847{#|007d014045000134045440004006e1090a326e010a32d201c1403241122679651154b1358018002ed765000001010 80a00067d3c00068abb0000000affffffffffffffffffffffff0000000000000008000000000000000000000000000000000000000a0000 000000000000000000000000000000000000000000040000000000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000000000016} |
